MDKSA-2007:113

Problem description

A flaw in the way mutt processed certain APOP authentication requests
was discovered. By sending certain responses when mutt attempted to
authenticate again an APOP server, a remote attacker could possibly
obtain certain portions of the user's authentication credentials
(CVE-2007-1558).

A flaw in how mutt handled certain characters in gecos fields could
lead to a buffer overflow. A local user able to give themselves a
carefully crafted Real Name could potentially execute arbitrary code
if a victim used mutt to expand the attacker's alias (CVE-2007-2683).
